Following concerns about the market power of the Big Six energy suppliers in the UK and high prices for gas and electricity, the industry regulator, Ofgem, referred the industry to the Competition and Markets Authority (CMA) in June 2014. The CMA published its final report in June 2016. This argued that while there was sufficient potential for competition, consumers nevertheless needed further encouragement to switch suppliers. This would strengthen competition in the market.
To encourage switching, the CMA proposed the creation of a database that would include the details of customers who have been on a supplier’s standard variable tariff (SVT) for three or more years. Competitor energy suppliers would have access to this database to offer better deals for these customers.
There had already been calls for price caps to be imposed on suppliers. For example, in the run-up to the 2015 general election, the then Labour leader, Ed Miliband, proposed imposing a price freeze. This was criticised by the Conservatives for being too anti-market, that it would encourage energy companies to raise prices prior to the freeze and that it would be of no benefit in times of falling wholesale energy prices (which was the position in 2015).
Indeed, in its 2016 report, the CMA recommended price caps only for the 16% of people on prepayment meters and these would be variable caps not freezes. This was followed in February 2017, by Ofgem’s announcement that a temporary price cap for such customers would come into effect in April 2017. The level of the cap would vary by meter type and region. It would also be reviewed every six months to reflect changes in costs and remain in place until 2020. There would be no cap on other customers.
But in the run-up to the 2017 election, the Conservatives announced that they would, after all, introduce a price cap on SVTs – 66% of customers are on such tariffs. Before the details were announced, there was much speculation as to what form such a cap would take? It would not be a simple freeze. But there was debate as to whether caps would vary with wholesale costs or whether they would be relative to the company’s lowest tariffs or to those of its rivals.
As it turned out, the proposal was for a cap on standard variable tariffs. It would be set by Ofgem and reviewed every six months. The cap would be based on the cheapest standard variable tariffs in each part of the UK, taking into account the variable costs for transporting energy there. Ofgem will adjust the cap every six months to reflect changes in the wholesale cost of energy.

The latest figures from the ONS show that UK inflation rose to 2.3% for the 12 months to February 2017 – up from 1.9% for the 12 months to January. The rate is the highest since September 2013 and has steadily increased since late 2015.
The main price index used to measure inflation is now CPIH, as opposed to CPI. CPIH is the consumer prices index (CPI) adjusted for housing costs and is thus a more realsitic measure of the cost pressures facing households. As the ONS states:
CPIH extends the consumer prices index (CPI) to include a measure of the costs associated with owning, maintaining and living in one’s own home, known as owner occupiers’ housing costs (OOH), along with Council Tax. Both of these are significant expenses for many households and are not included in the CPI.
But why has inflation risen so significantly? There are a number of reasons.
The first is a rise in transport costs (contributing 0.15 percentage points to the overall inflation rate increase of 0.4 percentage points). Fuel prices rose especially rapidly, reflecting both the rise in the dollar price of oil and the depreciation of the pound. In February 2016 the oil price was $32.18; in February 2017 it was $54.87 – a rise of 70.5%. In February 2016 the exchange rate was £1 = $1.43; in February 2017 it was £1 = $1.25 – a depreciation of 12.6%.
The second biggest contributor to the rise in inflation was recreation and culture (contributing 0.08 percentage points). A wide range of items in this sector, including both goods and services, rose in price. ‘Notably, the price of personal computers (including laptops and tablets) increased by 2.3% between January 2017 and February 2017.’ Again, a large contributing factor has been the fall in the value of the pound. Apple, for example, raised its UK app store prices by a quarter in January, having raised prices for iPhones, iPads and Mac computers significantly last autumn. Microsoft has raised its prices by more than 20% this year for software services such as Office and Azure. Dell, HP and Tesla have also significantly raised their prices.
The third biggest was food and non-alcoholic beverages (contributing 0.06 percentage points). ‘Food prices, overall, rose by 0.8% between January 2017 and February 2017, compared with a smaller rise of 0.1% a year earlier.’ Part of the reason has been the fall in the pound, but part has been poor harvests in southern Europe putting up euro prices. This is the first time that overall food prices have risen for more than two-and-a-half years.
It is expected that inflation will continue to rise over the coming months as the effect of the weaker pound and higher raw material and food prices filter though. The current set of pressures could see inflation peaking at around 3%. If there is a futher fall in the pound or further international price increases, inflation could be pushed higher still – well above the Bank of England’s 2% target. (Click here for a PowerPoint of the chart.)
The higher inflation means that firms are facing a squeeze on their profits from two directions.
First, wage rises have been slowing and are now on a level with consumer price rises. It is likely that wage rises will soon drop below price rises, meaning that real wages will fall, putting downward pressure on spending and squeezing firms’ revenue.
Second, input prices are rising faster than consumer prices. In the 12 months to February 2017, input prices (materials and fuels) rose by 19.1%, putting a squeeze on producers. Producer prices (‘factory gate prices’), by contrast, rose by 3.7%. Even though input prices are only part of the costs of production, the much smaller rise of 3.7% reflects the fact that producer’s margins have been squeezed. Retailers too are facing upward pressure on costs from this 3.7% rise in the prices of products they buy from producers.
One of the worries about the squeeze on real wages and the squeeze on profits is that this could dampen investment and slow both actual and potential growth.
So will the Bank of England respond by raising interest rates? The answer is probably no – at least not for a few months. The reason is that the higher inflation is not the result of excess demand and the economy ‘overheating’. In other words, the higher inflation is not from demand-pull pressures. Instead, it is from higher costs, which are in themselves likely to dampen demand and contribute to a slowdown. Raising interest rates would cause the economy to slow further.

Economists were generally in favour of the UK remaining in the EU and highly critical of the policy proposals of Donald Trump. And yet the UK voted to leave the EU and Donald Trump was elected.
People rejected the advice of most economists. Many blamed the failure of most economists to predict the 2007/8 financial crisis and to find solutions to the growing gulf between rich and poor, with the majority stuck on low incomes.
So to what extent are economists to blame for the rise in populism – a wave that could lead to electoral upsets in various European countries? The podcast below brings together economists and politicians from across the political spectrum. It is over an hour long and provides an in-depth discussion of many of the issues and the extent to which economists can provide answers.

Economic forecasting came in for much criticism at the time of the financial crisis and credit crunch. Few economists had predicted the crisis and its consequences. Even Queen Elizabeth II, on a visit to the London School of Economics in November 2008, asked why economists had got it so wrong. Similar criticisms have emerged since the Brexit vote, with economic forecasters being accused of being excessively pessimistic about the outcome.
The accuracy of economic forecasts was one of the topics discussed by Andy Haldane, Chief Economist at the Bank of England. Speaking at the Institute for Government in London, he compared economic forecasting to weather forecasting (see section from 15’20” in the webcast):
“Remember that? Michael Fish getting up: ‘There’s no hurricane coming but it will be very windy in Spain.’ Very similar to the sort of reports central banks – naming no names – issued pre-crisis, ‘There is no hurricane coming but it might be very windy in the sub-prime sector.” (18’40”)
The problem with the standard economic models which were used for forecasting is that they were essentially equilibrium models which work reasonably well in ‘normal’ times. But when there is a large shock to the economic system, they work much less well. First, the shocks themselves are hard to predict. For example, the sub-prime crisis in 2007/8 was not foreseen by most economists.
Then there is the effect of the shocks. Large shocks are much harder to model as they can trigger strong reactions by consumers and firms, and governments too. These reactions are often hugely affected by sentiment. Bouts of pessimism or even panic can grip markets, as happened in late 2008 with the collapse of Lehman Brothers. Markets can tumble way beyond what would be expected by a calm adjustment to a shock.
It can work the other way too. Economists generally predicted that the Brexit vote would lead to a fall in GDP. However, despite a large depreciation of sterling, consumer sentiment held up better than was expected and the economy kept growing.
But is it fair to compare economic forecasting with weather forecasting? Weather forecasting is concerned with natural phenomena and only seeks to forecast with any accuracy a few days ahead. Economic forecasting, if used correctly, highlights the drivers of economic change, such as government policy or the Brexit vote, and their likely consequences, other things being equal. Given that economies are constantly being affected by economic shocks, including government or central bank actions, it is impossible to forecast the state of the macroeconomy with any accuracy.
This does not mean that forecasting is useless, as it can highlight the likely effects of policies and take into account the latest surveys of, say, consumer and business confidence. It can also give the most likely central forecast of the economy and the likely probabilities of variance from this central forecast. This is why many forecasts use ‘fan charts’: see, for example, Bank of England forecasts.
What economic forecasts cannot do is to predict the precise state of the economy in the future. However, they can be refined to take into account more realistic modelling, including the modelling of human behaviour, and more accurate data, including survey data. But, however refined they become, they can only ever give likely values for various economic variables or likely effects of policy measures.

Many or us make New Year’s resolutions: going on a diet, doing exercise, spending more time studying. But few people stick to them, even though they say they would like to. So how can people be motivated to keep to their resolutions? Well, the experiments of behavioural economists provide a number of insights into the problem. They also suggest various incentives that can be used to motivate people to stick to their plans.
Central to the problem is that people have ‘time inconsistency’. They put a higher weight on the benefits of things that are good for them in the future and less weight on these benefits when they have to act now. You might strongly believe that going to the gym is good for you and plan to go next Monday. But when Monday comes, you can’t face it.
Another part of the time inconsistency problem is the relatively high weighting given to short-term gratification – eating chocolates, watching TV, spending time on social media, staying in bed. 
When thinking about whether you would like to do these things in, say, a couple of days’ time, you put a low weight on the pleasures. But thinking about doing them right now, you put a much higher weight on them. As the well-known saying goes, ‘Hard work often pays off after time, but laziness pays off now’.
So how can people be motivated to stick to their resolutions? Behavioural economists have studied various systems of incentives to see what works. Some of the findings are as follows:
|
|
| • |
People are generally loss averse. To get us to stick to New Year’s resolutions, we could devise a system of penalties for breaking them, such as paying 20p each time you swear! |
| • |
Given people’s time inconsistency, devising a system whereby you get treats after doing something you feel is good for you: e.g. watching TV for 30 minutes after you’ve done an hour’s revision. Rewards should follow effort, not precede them. |
| • |
Having simple clear goals. Thus rather than merely saying ‘I’ll eat less’, you devise a meal plan with menus that meet calorie and other dietary goals. Rather than saying, ‘I’ll exercise more’, you commit to going to the gym at specific times each week and doing a specific amount of each exercise. |
| • |
Ritualising. This is where you devise a regime that is feasible to stick to. For example, you could always write a shopping list to meet your dietary goals and then only buy what’s on that list; or you and your flatmates could have a rota for household chores. |
| • |
Social reinforcement. This is where people have a joint plan and help each other stick to it, such as going to the gym at specific times with a friend or group of friends, or joining a support group (e.g. to lose weight, or give up drinking or smoking). |
| • |
Avoiding temptation. For example, if you want to give up chocolate, don’t have any in the house. |
| • |
Using praise rather than criticism. People generally respond better to positive incentives than negative ones. |
Behavioural economists test these different incentive mechanisms to see what works best and then to see how they can be refined. The testing could be done experimentally, with volunteers being given different incentives and seeing how they respond. Alternatively, data could be collected on the effects of different incentive mechanisms that people have actually used, whether at home or at work.
The advertising and marketing industry analyses consumer trends and how people respond to pricing, quality, display, packaging, advertising, etc. They want to understand human behaviour so that they can ‘direct’ it in their favour of their clients. Governments too are keen to find ways of encouraging people to do more of things that are good for them and less of things that are bad.
The UK government’s Behavioural Insights Team looks at ways people can be ‘nudged’ into changing their behaviour, see the blog A nudge in the right direction?
But back to New Year’s resolutions, have you made any? And, if so, have you thought about how you might stick to them? Have you thought about the incentives?

Questions
- Explain what is meant by time inconsistent behaviour. Is this the same as giving future costs and benefits a lower weighting than present ones (and hence having to discount future costs and benefits)?
- Give some examples of ways in which your own behaviour exhibits time inconsistency. Would it be accurate to describe this as ‘present bias’?
- Would you describe not sticking to New Year’s resolutions as ‘irrational behaviour’?
- Have you made any New Year’s resolutions, or do you have any plans to achieve goals? Could you alter your own personal incentives and, if so, how, to make it more likely that you will stick to your resolutions/goals?
- Give some examples of ways in which the government could ‘nudge’ us to behave in ways that were more in our own individual interests or those of society or the environment?
- Do you think it’s desirable that the advertising industry should employ psychologists and behavioural economists to help it achieve its goals?
